\A/ALTEE M. HARKS mmvroze Patented Nov. 24, 1953 HOSE EXTENDING AND LATCHING MECHANISM Walter M. Harks, Fort Wayne, Ind., assignor to Bowser, Inc., Fort Wayne, Ind., a corporation of Indiana Application October 24, 1947, Serial No. 781,911

8 Claims.

This invention relates to an extendible hose mechanism and a hose latching means; more specifically, it relates to a mechanism for extending the discharge hose on a filling station dispensing pump and latching the hose in its extended position and for releasing said latch upon return of the nozzle to the nozzle support.

The advent of the low model gasoline dispensing pump has posed quite a problem for the manufacturers due to the fact that the length of hose required by the trade would drag on the ground if suspended on the pump in the usual manner.

It is an object of this invention to provide a hose extending means wherein a part of the hose is concealed in the housing of the pump.

It is another object of this invention to provide a hose extending means wherein the hose is retrieved by a sliding weight.

Another object of this invention is to provide a hose extending means that will retain the hose in any extended position.

It is still another object of this invention to provide a hose extending means for a gasoline dispensing pump that will retain the hose in extended position only when the pump is in operation.

Still another object of this invention is to provide a hose extending mechanism with a gravity operated hose latch to hold the hose in any extended position.

A further object of this invention is to provide a hose extending mechanism and hose latching means which is interconnected with the motor switch and the interlock mechanism on a gasoline dispensing pump for setting and release thereby.

It is still another object of this invention to provide a hose extending mechanism which will not place undue strain on or create excessive wear on the hose.

Yet another object of the invention is to provide a latching means, such as that described, which is moved to released position upon stopping of the pump motor by the operation of the hose hook.

These and other objects will become apparent from a study of the drawings which are attached hereto and made a part hereof, and in which:

Figure 1 is a view of a gasoline dispensing pump from the dial side showing the hose extending mechanism and the hose latch.

Figure 2 is a section taken substantially on the line 22 of Figure 1 showing the hose extending mechanism and the hose latch.

Figure 3 is a section taken on the line 3-3 of Figure 1 showing the hose retrieving weight.

I tive and the hose is in retracted position.

Referring to the drawings, the numeral I des ignates a dispensing pump having a base 3 and a frame 5 comprised of four corner angles 1 and cross members 9 and II.

Mounted on the frame and having conventional liquid and mechanical connections is a pump IS, a motor 15, a meter 1 i, an air separator IS, a register 2! having dials 22, and sight glasses 23, one having a discharge pipe 25.

A channel 2 7 extends upward from the base and has its web fastened to a frame angle 1 by screwsand nuts 28. The channel extends a short distance above the cross member 9, is open on the top side and is aligned with the depending portion of the discharge pipe 25.

A similar channel 29 extends upward from the base and has its web fastened to the frame angle- 1 opposite the channel 2'! on the same dial side of the pump by screws and nuts 3| and clips 33. The channels 2? and 25 are thus opened toward each other and have their flanges and grooves in alignment to form parallel guide Walls. The channel 29 extends up higher than channel 2'5. The channel 29 has joined to it at its upp r end an open-topped channel 35 which curves over the top of the computer or register and is bent in wardly out of the plane of the channels so that it will pass back of the frame angle I, associated with the channel 21, and line up with a rectangular opening 3'! in the housing 39 on the hose hook side of the pump. A short channel section M is welded in position around the adjoining ends of channels 29 and 35, as viewed in Figure 1, to form a joint 43 between the channels. The outer end of the channel 35 is fastened to the angle 1 by a clip 45 and a screw (not shown).

A hose retrieving head or weight 41 comprises two rectangular side members 49 and 5| held in parallel relationship by spacers 53 having reduced ends 55 which pass through holes in the side members and are riveted over on the outside. Rollers 51, shorter in length than the distance between the side members, are placed over the spacers and are free to rotate and to travel slightly endwise on the spacers. The centers of the rollers are disposed in a smooth curve, as shown in Figure 1, so as to produce a regular, smooth curve in the dispensing hose upon which the rolls ride. Bumpers 59 are welded between the side'members and extend-beyond their bot tom edges inalignment with resilient bumpers BI mounted on the base by screws and nuts 93. A pair of clips 65 are mounted at the top and bot-.- tom of the member 5i and projectinwardto. straddle a guide rod 61 which extendsthrough-v the base and the cross member 9. The rodis threaded at both ends and is engaged ontheun-a der side of the base and omth'eltopside-ofethe cross member by nuts 68. The ends of the head enter the guide ways of channels?! and ,2 9. The channel 35 is equipped with'spacers '99 having reduced ends II extending through-holes I3 in the side walls of the channel and which are riveted on theoutsideof the channel..- Rollers I5, shorter than the. distance between -the walls of the channel are mounted to rotate and travel slightly endwise on the spacers in a manner similar to the spacers 53- and the-rollers51-of theweight '41. j The spacers 99' and the rollers I5; are arranged in a smooths-curve with' the roller :on the far" end of--the channel adjacent and in line with the bottom of the opening v31 in-rthe housing. Additional guide rollers 16 are mounted in a verticalposition on 'the. exterior or the housing on either side-of the opening '31. pThe discharge hose 1 I is-screwed into the end or the discharge pipe 25,. -passes downward {into the'channel--2'I ,--under the rollers -51 and between the side members 49 and. 5I- of theweight; up inside the channel "29,- and-over the rollers I5 within and following the curved channel 35: to project, finally,-through-the openingp3'l. Ehe hose then looped-downwardand upwith the nozzle 19 placed on the hose hook-8i with-the tip of the nozzle inside the boot 83 as shownsin Figure 7 l .7 v. ,i

The latching mechanism, generally indicated by the numeral 85, comprises a bell crank- 93 pivoted onthe, rod 81 which-isjournalled inra pairof brackets 89 rising from thewalls ofthe channel 3.5,.-at a point to --th eright of the vertical i-centerline..of...the pump asviewedrin Figure 1..- The latchingmechanism .comprises a roller. 91- mounted for freerotation betweem sideplates of. one armnof the bell crankat a point below--the pivot md 81. .The other arm of the bell crank extends out -from the pivot rod atrig ht angles to the roller mounting arm. and terminates in a weight 95 which is welded between-the side plates. .-The weight urges the. latching mechanism in a clockwise dir'ection,.as viewed ingF igure 1,- causingthe roller 9 and the rollerarm to enterTthe-channel landmines the roller 9 I ,to 11388111111: clamping relation. upon the top side of the hose TI.

jlifting rod 91 extendsunderthe weighted portion of the bell crankand extends downward through a guide 99 on the side of the channel 35 ltoconnectwith a link I! which has a fulcrum I03 substantially at its center; The fulcrum is fixed .on theinterlock case I The other end ofvthe link receives a rod I01 which extends downward and is coupled to the motor switch rod I09 as shown at [H (Figs. 1 and 6). The motor switch rod I09 is connected with the hose support 8| by the rod H3, the bell crank H5 and the reciprocating rod II! which is a part of the hose support. The rod H3 also couples rod I09 to the interlock actuating lever H9 which has a pivot at I2I on the cross member [23 which fastens tothetangles I onithe hose-support side ofthe pump. The interlock seeker I25 is fastened to the interlock actuating lever at the midpoint and has two legs extending upward into the. interlock case I05. This seeker and the interlock;mechanism"are fully disclosed in the Patent Number 2,299,894 issued October 27, 1942, to C. P. Grimth'nor iiCont'rol, Mechanism for Liquid DispensingsApparatus and no detailed explanation of its constructionand operation is believed to be.necessary.- the,

The register reset crank I2! is located on the pumpihousing on the side opposite the hose support and connected to reset the register and to reconditiontheinterlock mechanismrina manner commonly'known in the arta F w The ,pump operation is. initiated. by' resetting the register} I, to zero, whic' h is accomplishedjby rotating 'the. ,crank- ,I Z'L' 'Ihi's 'conditions the interlock mechanism, so that; the hose u por may be operated to close thelmotorswitch (not shown) upon actuationof switch rod I09 in an upward direction.,, The nozzle 19 .isremoved from the hose support 81 and the hose support pulled outwardly. V

The outward movement of thehose support will be transmitted through therod H l' to rotate the bell crank I I5in a clockwise direction (Fig. 1) about its fulcrum, which will raise rod H3, link H9 with the seeker I25] and themotorswitch rod I09.. Such movementjs prevented bythe i interlock mechanism if the register has not been reset tozero. The upward movement of the switch rod will impart a similar movement to coupling IH and,r od I0! to pivotthe link I0l about its fulcruml03 counterclockwise, which will lower rod 9'! and permit the latch 85 to rotate in a clockwise directioniFig. 1) about the rod 9]"bringingj theroll-er 9i into en gagement with the top. ofthei hose I'I.

'The hose is pulled out of the housing. or extended, with. the weight ,4'I.moving up inthe channels 2'! and 29, guided bythe'rod 3'! and clips BE. This upward movement is limited by the cross member 9. The hose willlrotate the rollers 51and'l5 on their respective" spacers 53 and as so thatra rea'sonable'light'pull is "air'that is required to withdraw tnehcse, WIt will be noted that the rollersjare shorter than .the spacers, which permits therollers to travel -end wise on the spacersto accommodate any weaveof the hose on both. extension and retraction-thereof. It also permits lubrication of the rollsand assists inpreventing sticking thereof. T

The latching mechanism will permit frec extension of the. hose at alltimes bccause passage of the hose in'tliis direction tends to lift the roll. However, when the latch is free of thelevr 91. it will be urgedinto latching position by its weighted portion to prevent retraction of the hose, a slight retraction serving to jam the roller against the hose to frictionally hold it. This action is aided by the fact that the hose curves upwardly to the left in Figure 1 so that the roller cannot pass fover center in a clockwise direction and release the grip on the hose. When the hose hook is pushed inwardly (usually after the dispensingoperation) it raisesrod 91 by means .of-

The rollers 51 and willrotate in reverse direction from that'of the hose extension stroke. 7

Rolls 16 are provid d on each side of the pen: ing ,31 topreventtheghose being scuffed against the housing 39 when the hose is pulled to the side and to prevent binding which might interfere with the easy extension or return of the hose.

When the head has fully returned to its lowermost position, the loop of hose outside of the housing will not be long enough to reach the ground. This condition is shown in Figure '7.

It is obvious that various changes may be made in the form, structure and arrangement of parts without departing from the spirit of the invention. Accordingly, applicant does not desire to be limited to the specific embodiment disclosed herein primarily for purposes of illustration; but instead, he desires protection falling fairly within the scope of the appended claims.
